"I found Zyban to be very effective and easy to use. I only experienced a few mild side effects (slight constipation, food tasted a bit different).  But I'd tried quitting before using gum, microtabs, patches - and none of these worked for me.  Thanks to Zyban, it's been over four months since I smoked a cigarette and haven't turned back - proud to be a non-smoker!"
